VAPOR-BURNER FOR SOLDERING AND BRANDING IRONS.

SPECIFICATION forming part of Letters Patent No. 317,489, datedMay 12,18 85.

Application filed September 12, 1883.

To all whom, it may concern.-

Be it known that I, LEoPoLD BAUMEISTER, a citizen of the Grand Duchy ofBaden, residing at Bridgeport, in the county of Fairfield and State ofConnecticut, have invented certain new and useful Improvements in Vapor-Burners for Soldering and Branding Irons; and I do hereby declare thefollowing to be a full, clear, and exact description of the inven' tion,such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to the class of devices which require to be keptheated while in usesuch, for instance, as soldering and brandingirons-and the object thereof is to produce an iron which may be readilyheated without the use of a furnace, may be kept hot for any length oftime, and which may be laid down' for a few moments and again usedwithout the necessity of reheating or placing in contact with flame,while at the same time the device shall be simple in construction,economical in cost, and easy to manage. With these ends in view, myinvention consists in the construction and combination of parts, ashereinafter fully described, and then specifically designated by theclaims.

For the purpose of enabling those skilled in the art to which theinvention relates to understand and use my improved device, I willproceed to describe the same, referring by letters to the accompanyingdrawings, forming part of this specification, in which-- Figure 1 is anelevation of a soldering-iron embodymg my invention. Fig. 2 is a centrallongitudinal section of the same. Fig. 3 is an elevation of the burner,full size. Fig. 4 is a longitudinal section of the burner, wiclctube,and wicks, full size. Fig. 5 is an elevation, and Fig. 6 is a section,full size, of the filter in the vaporizer. Fig. 7 is an elevation of thevaporizer, full size. Fig. 8 is a section, and Fig. 9 an elevation, of ablue-flame tip, which.

may be substituted in lieu of the soldering-iron 3 iizer, as shown inFig. l. Withm the reserfor plumbers and jewelersuse; and Fig. 10is asection of a branding-iron adapted to'be attached to the collet in lieuof the outer tube and the soldering-iron or blue-flame tip.

Similar letters indicate like parts in all the figures of the drawings.

A is the handle, ordinarily made of wood.

(No model.)

; B is a bulb or reservoir, which holds the benzine or other liquidhydrocarbon from which the vapor is generated. A tube, C, which isrigidly attached to the bulb, extends down through the handle, as willpresently be more fully explained.

D is an aperture for filling the bulb, which is closed by thumb-screw D.A collet, B, threaded both externally and internally, is formed upon thebulb, to which the outer tube E, having perforations e and e, isattached by the-external screw-thread. To the opposite end of tube E thesolderingiron F or blueflame burner Gis attached, as shown in Figs. 1,2, 8, and 9. Attached to the collet by the inner screw-thread is a plug,H, which, owing to its peculiar construction, I term a vaporizer. Theinner end-that is to say, the end toward the reservoirof the vaporizeris provided with a perforated block or plug, H. This plug is preferablyscrewed into the vaporizer, and is provided with a funnel-shapedopening, h, at its inner end, for a purpose presently to be explained.At the other end of the vaporizer is another screw-p1ug,H with a minuteperforation at H hardly visible to the naked eye.

Between plugs H H is a filter, I. This filter consists of a tube ofbrass or other metal, the ends of which are closed by rolls #1 ofwiregauze. Between; the rolls of gauze the tube is filled in closelywith particles of a solder made of silver, copper, and tin in aboutequal quantities, as shown in Figs. 2 and 4. The burner K is attached tothe outer end of the vaporizer. The burner consists of a tube, K, havingperi'orarions k", a cage or coil, K of platinum wire attached to theouter end of the tube, and a tip, K having perforations and open at thetop, as shown. I usually The tip is held on simply by the expansion ofthe tube. I usually attach the tube to the vaporizer by means of aflange, 70, which engages with a beveled stud, h, on the vaporvoir is awick-tube, L, which I ordinarily screw onto the outside of plug El.

I have found it desirable to use two tubular wicks m m, one within thetube, and the other outside thereof.

With the wicks as shown it is a matter of split the tube part way down,as shown at w.

no consequence whatever in what position l the iron is held, as it willwork equally well whether held horizontally or either end up. If heldwith the point of the iron down, the contents of the reservoir will, ofcourse, settle l in the end of the reservoir toward the point whichhasno direct connection with the vaporizer. In this position the benzine orother fluid will feed up the outer wick by capillary attraction until itcomes in contact with the inner wick at the other end of the tube. Fromthis point gravity will assist capillary attraction in the inner wick,and the vaporizer will thus be supplied.

Within the handle and extending entirely through it is a tube, 0, theinner end of which is soldered to the bulb. The outer end of this tubeis screw-threaded, both internally and externally. The outerscrew-thread engages with ablock, N, in the outer end of the handle, andalso with a nut, O. This nut has two internal screw-threads, betweenwhich is a shoulder, O; the larger screw-thread extends only part waythrough it, and is engaged by the external screw-thread of tube 0. Arod, P, extends through the nut and tube, and within the inner wicknearly through the wick-tube in the reservoir, where its beveled point Pengages with the i'unnel'shaped opening it of plug H, which it isadapted to entirely close. The outer end of the rod is screwthreaded,and engages with theinner screwthread on tube 0, and with the smallerscrewthread in nut O. The outer end of tube 0 is made slightlyfunnelshaped to accommodate a packing, Q, which lies between tube 0 androd P, and restsagainst shoulder O in nut O, which 'acts to crowd thepacking tightly in place, thus rendering the escape of vapor at 1 thispoint an absolute impossibility.

The operation is as follows: The reservoir is filled with any liquidhydrocarbonprefer- 1 ably benzine-and rod P screwed up tight to l, closethe orifice into the vaporizer. The outer tube, E, is then held for afew minutes in flame (a spiritlamp will be found most convenient) togenerate the vapor. As soon as the outer tube, and with it the burner,becomes thoroughly heated, rod P is turned backward to 3 open thepassage into the vaporizer.

The vapor which forms at the surface of the liquid creates sufficientpressure to force it into the wicktube and through the inner wick. Noair is admitted until the vapor has passed through the filter and intothe burner-tube, where it is mixed with air before it reaches the coil,and meets another current at the coil, which assists combustion. The twowicks will I act to prevent the passage of any appreciable 1 quantity ofbenzine into the vaporizer, and the filter will allow nothing but thevapor to es cape, and that in a thoroughly purified condi- 1 tion, as nosolid matter whatever can pass 1 through the rolls of gauze andparticles of a l solder made of silver, copper, and tin in about equalquantities, which also control the quan- 3 tity of vapor that canescape. After passing 1 through the filter the vapor escapes into theburner-tube K at the minute perforation H in plug H In this tube thevapor is mixed with atmospheric air, which enters through perforations'c in the outer tube and 7-32 in the air, which enters through the longperforations 6 in the outer tube, and perforations k in the tip.Combustion takes place at the platinum coil, which requires to be heatedto white heat before the vapor is allowed to enter the burner-tube. Assoon as the current of mixed vapor and air reaches the coil it takesfire. In

use a blue flame of intense heat is thrown into l the cavity F in thesoldering-iron and out at the openings F 'When the blue-flame tip isused the flame passes directly out at orifice G.

The branding-iron R, (shown in section in Fig. 10,) is heated in thesame manner as the other irons, the only change in construction beingthat the outer tube and arms R are cast in one piece, which is attacheddirectly to the collet. The outer rim or band B of the branding-iron issecured to the arms by screws, as shown.

The letters (not shown) are cast upon the bottom R The flame acts uponthe bottom, and thus heats the letters, but never comes in contact withthe letters themselves, so that constant oxidation and wearing away ofthe letters is prevented.

1t are small holes for the escape of the vapors when the iron is in use.a

The materials used are not of the essence of my invention.

In practice I have'found it best to'make the reservoir and rod P ofsteel, the reservoir being made in two parts and soldered together, asshown at B I have adopted the globular form of reservoir on account ofits great strength as compared with other forms, which is desirable onaccount of the pressure of the hydrocarbon vapor when the. iron is inuse.

The burner, the soldering-iron, and the bottom letters and rim of thebranding-iron I make of copper, the burner-cap and outer tube of iron,and the plugs of brass. In use this iron will be found to work withoutsmoke or smell,

theiron laid down for fully five minutes. The vapor may then be turnedon, and will instantly take fircat the coil.

1 am aware that the general arrangement which I have shown of reservoir,tubes, wicks, and iron, a hollow handle, bevel-pointed rod, 850., alsothe use of strands or a web of platinum wire, is not new, and also thatnumerous substances have been used as filters for vapor such as emery,sand, asbestus, broken glass, granules oflead and copper, and brass andiron filings-and I make no claim thereto, but

Having thus described my invention and referred to the state of the art,I claim-- 1. In a vapor-burner, a filter consisting of a tube closed ateach end by a roll of wire-gauze or equivalent material, and filled withpart icles of a solder made of silver, copper, and tin 1 in about equalquantities, as described, and for j the purpose set forth.
